Nice thing about stuff from Radio Shack is they have the part numbers on them. I looked it up. Here's the link for the fan I have.

Like I said before, if standing upright by itself you can't even hear it. Lying down on top of the receiver it makes a humming noise because its sucking the air out so fast.
You'll have to decide for yourself if it bothers you. I did have to splice it with a plug, also from Radio Shack, and I plug it into the back on the receiver. Reciever on fan on, receiver off fan off.
